Elevate your dessert game with our irresistible Upside Down Plum Cake - a perfect treat for any occasion! Our recipe features a moist and tender cake base topped with juicy and sweet plum slices and passionfruit, all baked to perfection and flipped upside down for a stunning presentation.
The best trick with this dish is that there’s a secret ingredient in it…passionfruit. The gloriously underrated passionfruit comes to play with plums in something I’ve not seen often in recipes. The flavors burst and mellow with each bite of this and it could become a cake that gets made and remade with each new season of seasonal fruit onhand - somehow the plums are perfect for right now though.
Growing up with a German mother meant that yeasted (I don't think that's a word, but I'm rolling with it) plum cake was made every summer and we didn’t often eat it any other way in baking. It felt a little weird, in fact, to make this cake which feels so different from how I know this fruit.
I'm not sure how she gathered the energy to bake in the middle of summer, but fruit doesn't wait around, in fact, the surplus that always comes from food in the summer is basically asking to be turned into anything and everything and so here we are with an upside down cake. What is your go to use for summer produce?

If using a springform cake tin, lay aluminum foil underneath as the syrup and plum create quite a sauce which will drip whilst baking and this will keep cleanup easy.

The passionfruit adds a beautiful flavor and helps the syrup form, however, a great sub would be 2 tablespoons of orange juice.
